• A filter reduces the available data for other rules in the Rulesheet to use. Filters show as gray text rather than black. shades of gray - all data, some data, or no data may result from a filter.
  • A filter in Precondition mode stops Rulesheet execution if no data survives the filter. Preconditions are explicit: data either survives the filter, and allows Rulesheet execution to continue, or no data survives and the Rulesheet execution stops.
  • Filter expressions always acts as a filter. By default, they act as filters only. If you also need true precondition behavior, then setting the filter to Precondition mode enables precondition behavior while keeping filter behavior.
